Hi Patrick,
I did explain how to cancel the subscription, by closing the account. In the account settings (in the screen grab included) there is a CLOSE ACCOUNT option. Clicking the Proceed >> link under close account will close the account immediately. The account can be closed anytime prior to renewal. So, if the account was due to renew on June 1st closing the account any day/time before midnight (PT) on May 31st would prevent the renewal.
The screen grab embedded in my previous reply isn't displaying so, I'm linking it here, too: https://photos.smugmug.com/photos/i-pxpMqVx/0/O/i-pxpMqVx.jpg
There is not an option to remove/prevent renewal other than closing the account.
Regards,
Christina
